Theodore Roosevelt Augustus Major Poston (July 4, 1906 – January 11, 1974) was an American journalist and author.

By the age of fifteen, Poston began his career writing articles for his family's paper, the Hopkinsville Contender.

[2] Poston became a reporter for the New York Amsterdam News, a weekly newspaper geared to the city's African-American community, in Harlem in 1928.

[4] During his thirty-five year career at the Post, Poston covered many important stories of the day, such as Jackie Robinson's entrance into Major League Baseball, the Brown v. Board of Education case and the efforts of the Little Rock Nine to integrate schools in Little Rock, Arkansas.

He also covered the Scottsboro Boys trials with much difficulty, as the Alabama authorities would not allow a black journalist to report in the segregated South.

After Roosevelt's death, Poston joined other black journalists in pressuring Harry S. Truman to desegregate the military.

In 1999, his series on the Groveland Case was named one the 100 most important journalistic works of the 20th century by New York University's School of Journalism.
